If a uniform beam was in space (no gravity or resistance of any kind) and only was applied a force F on only one side, does the inside of the beam feel a stress and deform? If so, what does the stress equal? Can you explain why/why not the beam feels a stress or not?
I know that that if applied a force on both sides, the stress would just be F/cross sectional area of beam. But in this case the force is only on one side.
I believe that if I imagine the beam to consist of 2 parts joined up (part A and part B), if say a pulling force was applied to the part A, part A would pull on part B. But then part B would also exert a force equal in magnitude but opposite in direction on part A (Newton's third law). Would'nt part A feel a tensile stress then as it would have a force pulling it in one direction and another pulling it towards B in the opposite direction? Can someone correct me on this?
Thank you very much
